Hey there, I've got only 1 calendar which is called "Home" and has only 5 events in it. But when syncing iPhone in iTunes, the sync stalled on "syncing calendars with my iphone" and won't go any further. Yes, it just stalled there for over an hour! Once I unchecked the "sync calendar" option, the sync can finish perfectly. Do you have similar issues? Or any ideas? Thanks!
